Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.62 g and has a volume of 0.563 cm³. Gold has a density of 19.3 g/cm³ and copper has a density of 8.96 g/cm³. Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains.

A brick of a certain metal has area on top of 3.54 cm x 6.93 cm. It has mass 921 g. How high is the brick in cm? The metal has density of 10.6 g/cm3 2.54 cm = 1 inch Ixhxw-V V- m/d You need to combine the above equations; this is a typical math skill you need in chemistry.
If a sample of unknown substance has a mass of 3.50 kg and a volume of 1.30 L, what is the density of the substance when expressed in conventional (but non-SI) units of g/cm3?
If a sample of gold alloy has a mass of 87.7 g and is 78.3% gold by mass, what percentage of the alloy is made up of other metals? Write your answer to the nearest tenth of a percent. (I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 8×103 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×1030kg and the radius of the moon is 2.16×103mi. (Volume of a sphere =43πr3.)

A student gently drops an object weighing 16.9 g into an open vessel that is full of ethanol, so that a volume of ethanol spills out equal to the volume of the object. The experimenter now finds that the vessel and its contents weigh 10.6 g more than the vessel full of ethanol only. The density of ethanol is 0.789 g/cm. What is the density of the object? Density = g/cm³
